Despite repeated rumblings from industry sources (including Lutz himself) that the Opel Insignia's transformation into a Saturn model was on hold, Bob Lutz now indicates that work is indeed proceeding on making that model ready for the American market. Changes are going to be made to both the interior and the exterior of the Insignia as it morphs into the Aura. Lutz also indicates that the two Epsilon II-based cars will share suspension bits and powertrains, though we are not sure just how many of the six available gas and diesel engines in the Euro-only Opel will make their way Stateside. Also debatable is the Insignia's Haldex all-wheel-drive system that will be offered across the pond. Whatever the case, we hope that the car doesn't see too many changes as it's an extremely attractive and compelling package as it currently sits. Bring it.
